The Lowdown

Alright folks, Rusty here. Let's cut to the chase. This is one of those outlooks where we just have to call it like it is: the next couple of weeks are looking pretty flat and uninspiring for Kennebunk Beach.

Right off the bat, the water temp is sitting at about 69°, which is a touch warmer than normal for this time of year – not a bad thing if you're just floating around.

The problem is the swell. We are looking at a long stretch of tiny, weak surf. From now through the weekend and into early next week, we're talking about waves struggling to hit 1ft. The combined wave energy is barely registering, mostly sitting in the single digits or very low double digits (like 7, 16, 23). The winds are a mixed bag of cross and cross-off, which would keep things clean for those tiny ripples, but there's simply no power behind them. The swell direction is coming from the SE, which isn't ideal for this sheltered spot anyway.

The first faint glimmer of anything surfable doesn't appear until Monday, August 17th. The morning swing shows a little bump, with swell heights around 4ft from the SSE and a short period of 7 seconds. The combined energy finally gets into three-digit territory at 128, which is moderate. The wind is a light cross-off, so conditions would be clean. However, it's a short-period, junky little swell that the data itself calls "surfable waves but very ordinary conditions." Not exactly a ringing endorsement.

After that one glimmer, it's right back to the doldrums through the rest of the week. By Wednesday, August 19th, we see a flush of 5ft from the S, but it comes with a terrible period of just 5 seconds and a cross-onshore wind, making it a choppy, messy shore break that would be more interesting for kite surfing than a proper paddle session.

The next possible window comes on Thursday, August 20th. The morning has a glassy, clean surface with 4ft of swell from the S, but again, that period is a terrible 5 seconds. The energy is moderate (98), but it's just a close-out crumble.

Honestly, this is a 16-day window with no real standouts. There’s nothing worth paddling out for in a focused way. For this area, a run like this happens. The consistency isn't there, the groundswell is absent, and the wind windows don't line up with any decent sized, clean swell. It's a waiting game. Forecasts can change, but right now, if you’re Jonesing for a wave, you might want to look at a lake.

Rusty.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
